# Modified by the slackbuilds.org project

# ChangeLog:
#
#  * 2014-01-29:
#     New upstream version (2.6.2). Solved the problem with dynamic
#    linking on x86_64.
#  * 2015-08-03:
#     New upstream version (2.6.8). You can now override most of the
#     configure options on the command line.

# 20220211 bkw: updated for v2.7, as 2.6.8 won't build on Slackware 15.0.
